srnctnoariofi forming art of LettersPatent' No. 616,022, dated nastiest. '1 3, 1898. Application fins May 26, 1897. Renewed March 23, 1898. Serial No. 674,941. (tloinddeh) Be it knownthat I, EDWARD H. SCHILD, a citizen of "the United States, residing-at Baltimore, State of Maryland, have invented certain new and useful Improvements in Advertising-Signs, of which the followingis a specification, reference being had therein to the accompanying drawings.

In the drawings annexed, Figure l isa front view of the. sign; Fig. 2, a horizontal section thereof; Fig.3, a transverse vertical section; Fig. 34,, a detail view of the eyeball-representing devices, and Fig. 4 a' diag'rammatical view of the motor I prefernsingto operate the movable. parts. l

The invention is designed especially fertile use of Opticians; but it may beused in other businesses,if desired ,as will be hereinafter.

The invention consists, essentially, of a frame,prefcrablya representation otan eyeglass or spectacles, having, preferably, a pair of elliptical or similarly-shapedopenings to correspond with'the eye-openings on the human or other face, and in combination therewith preferably a pair of artificial eyes supported in a casing'or casings directly behind 'theeye-openings and adapted to have imparted to theme. lateral movement with respect to the eye-openings to simulate the movements of the human or other eye when glancing from side to side, as more fully hereinafterset forth. By preference the part represent'in g the frame of the eyeglass is'macle opaque and the parts representing the eyesaremade translucent and inclosed in a casing ogqasings containing means for illum'ie" nati1ifiheininferiorg whereby the sign will.

be ren ered effective in the dark.

The invention also consists of means for positively shifting the movable parts representing the eyes intermittently and irregu larly, causing them to remain still or fixed at intervals, thereby more nearly resembling the movements of the human or other eyes, as more fully hereinafter set forth.

Referring to the drawings by letters, a designates the main frame, which is made in the form of an eyeglass and isprovided with the two elliptical opcningsa, one being formed seen more fully. ld'rect'ion namely, longitudinally bii of in each elliptical part ofthe eyeglass. Be-

hind each opening is fastened a closed casing b, which may be formed rectangular, as in. full lines in Fig. 2, or may be tapered toward the rear, as shown in dotted lines in Fig. 2; but it is immaterial as to the shape of these casings, it being simply necessary that they be made of such a shape and size as not to be too plainly visible, if at all, from the front. Suitable scrolls or sign-plates 0 may be attached. to the frame for the reception of suitable advertising matter.

Within each casing,directly behind the eyeopening, is supported a translucent convex plate d, the surface of which will preferably bepolislied and colored'toieseiiibIe 'tlie'liuman eyebalL/ This plate (Z is shown in the aim figures as being convened-in but one 'course it may also be convexed transve ely, asshown-in Fig. 3%, to resemble'more nearly the sclerotic coat of the eyeball. In front of,-tlje plate 01 and directly behind'the eyeopening in the opaque frame is a translucent disk-'6, which is supported upon a frame consisting of horizontal bars e and a'vertical'bar c the respective bars e working above and below the plate d. These frames extend backward to the rear of their respective casings,'and each is'swung therein upon the vertical pivot f, this pivot being located approximately in the center of a circle struck from the arc shaped plate d, so that'when the'frames are vibrated the isks ewill move in unison with each other a (1 parallel with thesaid platesd. Each disk 0 is convexed to.

correspond to its adjacent plated, Thedisks e are made of translucent material and are colored to represent the pupil and iris of the eye. 'I' have shown an incandescent electric lamp in each casing hack of the plates 1 and e to illuminate the apparatus in the dark;

but of course it is unders ood that any other suitable means may be employed for that purpose. 1 v

The two swing-frames are connected by a rod g, which extends hqrizontally through the adjacent sides of the casing. To reciprocate this bar 9 and thereby cause the disks 0 to move in unison from {side to side, I may rot -lI show one form of such motor In this at a suitable point;

construction I employa suitable tank It, provided in ils bottoinwilli an exit-opening controlled by a vertically-working valve 7t, this valve being adjustablysupported on the free end of a lever It? by means of a screw hlflsaid lever being pivoted at its opposite end to a suitable stationary part above the tank. A suitable siphon r' is connected to the tank to automatically rmr-oll the walerhvhen the tank fills up and there is danger-of overilowing. Rigid ly supported in a vertical position in the tank is an inverted air-chambenj, open at itsbottom and olosed'at its top. Connected to'thetop of this airbhamber is an'air-tnbe k, which extends to a small cylinder or airchamber 7;, attached to one of the casings 1) One end of this cham- Zc' is closed by a flexible membrane, and this membrane is connected by a red I; to the rod 9 or other movable part of the apparatus. Jou-rnaled below theiever 7&2 is a wheel 7, which is providednt its edge with a continuons series of cam-like projections, up n which rests a lateral pin or roller l, carried by the lever. This disk receives its motion from a suitable train of gearing, that in turn is driven by a smallwaterovheel m, journaled in a suitable frame above the lever,

The water that runs the Water-wheel is'emptied by a tube in into the tank ll, as shown,

The operation of this motor is as follows: As the water flows into the tank 71. the waterwheel ,will be rotated quite rapidly, and the motion of the water-wheel will be comm uni (rated to theeamavheel through the train of gearing, the intermediate gearing serving to reduce the, speed and correspondinglyaugment the power. As the cam-wheel rotates,

v the lever to \vhiehis attached the valve It is vertically vibrated, the vibrations being intermittent and irregular or variable. As the lever is vibrated the valve will be intermittently opened and closed, the valve being closed when the pin Z on the lover rests in the lower-parts oi the cam and being openedwido when resting on the outermost projeetionsof the oam-surfaco. In other words, the valve is operatedso as to'vary thesize and at times entirelyclose the exit-opening, so that the height of the water in the tank is being con:

stantly varied, exceptavhen the vvalve his so held that the exit-open lug is just large enough to carryoff the amount of water entering the tank, when of course. the level of; the Water will remain stationary. As the quantity of the water in the tank is thereby made to Very, the pressure in the air-chamber j and connecting-tube it will be correspondingly varied, and thisva'rying pressure will cause the dia phragm in chamber to move in and out in an irregular manner. The greater the pres sure the greater the projection of the dia phragm. In this manner I impart to the movable parts of the-eye an irregular or variable intomiittent motion, causing tion.

parts to come to rest and remain at rest any period-of time at various points. In this way the natural roving movement-of the eyeballs may be closely simulated, making the sign very effective in attracting and holding the attention of observers.

The advantage in employi ng a separate dish to represent the iris and pupil is that it avoids the necessity of shifting the larger platerepresenting the eyeball. If. this latter plate were shifted and theiris and pupil made a part thereof or indicated lhereon,it will be seen that the casings would require to be muchenlargedlaterally,and this enlargement would extend beyond the front frame, 1nal\'- ing them visible from the front and thereby destroying to a considerable'cxtent the effect iveness of the sign. v

It will be observed that another ad vantage lies in the factthat the plate representing the eyeball is convened and the dish: representing the pupil and iris is similarly convexed and made movable over the surface of the plate, the path of the disk being of course curved, whereby the natural rollingmovements of the human eyeball will be closely simulated. i

It will be obvious that the body of air conlined. between the variableliquid surface and I the movable mom brane is con ii ned in the sepa rate chambersj and is sim ply for the purpose of convenience, it being convenient in the present use of the motor to attach the chamber k to a convenient part of the casings and to locate the tank and other parts of the motor at some distance from the sign say in the dollar or belowthe shop window or counter. I

Should itbedesired, (and it is thought it may be desirable'in some cases,) the two vessels 7' and 7; may be connected directly and used as oneehambendoing away ivith the connectingtube. I therefore do not confine myself'to the specific arrangonmnt shown. In fact, both with reference to the sign proper and the motor, I reserve the right to vary the detail construction without departing from my inVe n-J It is also obvious that it is within the spirit of the invention to employ but one set of movable eyeball-reproachting devices, al-

though it is much preferabl especially for opticians signs, to employ the two sets of. de-

vices. When one set only is employed,.the

othinset of devices may be disconnected from the shifting-rod, on. the. eye, openihg may be partially or entirely closed to give a' comical appearance to the apparatus.

It will be seen, further, that the peculiaragb vantagc'of the motor I uselies in thoiact that the variations in the movements of the eyeball representing devices are rendered practically infinite-4mm is to say,the rapidity of the movements and the durations of the periods of rest, as well as the points of rest, are constantly being varied and the variz'ttions are practically infinite. l t Would'seom at first glance that the movements 0!. the eye-reprosaid movable i senting devices would be prodetermincdvaried because of the variation in the speed,

that is, that they would invariably come to rest.

with which it discharges itself, notwithstanding the fact that the inflow may be'and is preferably regular, and the rapidity of disehaz'geWiILBct-onIy depend on-thesize of the outlet, but ,willpalso, of course, depend-on other eonditions,-principally on the-weight of liquid in the-tank. In this manner the intermittent movements of the eye-represen ting parts within certain limits will be very varied and will therefore simulate closely the movements of a natural eyethe important desideratum in this invention. Even after the cam-wheel has made a complete revolution and begins another the movements of the eye-representing parts will not be duplicated, as the qnantit-yot water in thetank and other conditions will be different at the beginning of the second revolution and throw out or vary all the subsequent movements of the eyerepresenting devices, and as this will obviously be the case at'thc beginning of each revolution of the disk it will render the stopping of the eyerepresenting devices at exactly the same point a thing of the remotest contingency. The value of this constantly-varying series of movements will be obvious when it is remembereu that the eifectiveness of an advertising apparatus of this sort depends to agreat deg'ree on'the elimination of all monotony and regularity of movement, sincethe resemblance to the natural movements is destroyed by regularity and monotony. For instance, should the present device be operated facing -a crowd of observers the movements of the rest will be" artificial eyes and the points'of so constantly varied th at t-l e eyes will not, except in the remotest contingency) lie directed to exactly the same point twice, the angle of sight constantly varying, thereby last by the uniisual life-like appearance, and the variation need only a wonderful power to distinguish exceedingly slight variationsin theanglcs of sight of other eyes under observation.

It is obvious that the eye-openings may be covered with glass or other transpt'irent material,as.thc function of the openings remains the same whether glazed or not.
